API Architecture

The Swarms API provides a comprehensive multi-tier architecture for building intelligent AI systems. The platform is designed around three distinct agent paradigms, each optimized for different types of tasks and complexity levels.

Architecture Tiers

Tier	Name	Agent Count	Complexity	Primary Use	Example Use Cases	API Endpoint
Tier 1	Individual Agents	1	Low-Medium	Focused tasks	Content generation, data analysis, Q&A	`/v1/agent/completions`
Tier 2	Reasoning Agents	1-2 (internal)	Medium-High	Complex reasoning	Mathematical proofs, logical validation, research	`/v1/reasoning-agent/completions`
Tier 3	Multi-Agent Swarms	3-10,000+	High	Enterprise workflows	Process automation, large-scale systems, R&D	`/v1/swarm/completions`

Tier 1: Individual Agents

Single-purpose AI agents for focused tasks Individual agents are the foundation of the Swarms ecosystem. These are custom-built, single-purpose AI agents designed to handle specific tasks with high precision and efficiency. Key Characteristics

Single Agent: One AI model per agent
Focused Purpose: Specialized for specific tasks
Customizable: Full control over system prompts, tools, and behavior
Efficient: Optimized for direct task execution
Scalable: Can be combined into larger systems

Use Cases

Content generation (articles, code, reports)
Data analysis and processing
Customer service responses
Creative tasks (writing, design)
Simple Q&A and information retrieval
Tool execution and automation

Example Implementation

import requests

payload = {
    "agent_config": {
        "agent_name": "content-writer",
        "description": "Professional content writer for technical articles",
        "system_prompt": "You are an expert technical writer...",

}

response = requests.post(
    "https://api.swarms.world/v1/agent/completions",
    headers={"x-api-key": "your-api-key"},
    json=payload
)

Tier 2: Reasoning Agents

Advanced reasoning systems for complex problem-solving Reasoning agents leverage sophisticated reasoning techniques to solve complex problems that require deep analysis, multiple perspectives, and systematic thinking. These agents may internally use 1-2 specialized sub-agents to achieve their reasoning goals. Key Characteristics

Reasoning-Focused: Built for complex logical and analytical tasks
Multi-Perspective: Can approach problems from different angles
Iterative: Capable of refinement and improvement cycles
Specialized Types: 7 different reasoning agent types available
Internal Coordination: May use sub-agents for specialized reasoning

Memory: Minimal

Reasoning Agents

Latency: 5-30 seconds
Throughput: Medium (100-500 requests/minute)
Cost: $0.05-0.50 per request
Memory: Moderate

Multi-Agent Swarms
